Description of this change

Noticable changes:

1. I had to add direct dependency on "@io_grpc_grpc_java//api" in //ext:intellijext because the classes are not inside intellij any more. Still, the api classes were dependencies, but just transitive ones.
2. Intellij moved some class files from lib/.jar to lib/modules/.jar for Java plugin and for Core. I had to include them in intellij_platform_sdk
3. [EAP2] Changes in Python plugin jar directories strucutre
4. [EAP2] New method in TypeScriptConfig interface
5. [EAP2] Some tests now require ExperimentalUI service to be set, so they had to be moved to integration tests suite
